Can anyone Help with my CR 10 S4

Help? Hello I’m new to the forum. I have a CR10 S4, and it seems that I can not find out if there are any firmware upgrades. If no firmware upgrades is there a mainboard up grade.

What is wrong with your machine.?

How do I install the firmware. It is a 8bit board.
Thank you for your help.

Oh…By the way. Welcome to the forum. I hope someone is able to help. I have a K1 Max so not really familiar with the CR series…
